Quick Coupler
Hydraulic S-Standard quick coupler for MEDIUM excavators (10-59 t), enabling fast attachment changes without leaving the cab.
The STEC Hydraulic Quick Coupler is a hydraulic S-Standard quick coupler for MEDIUM excavators (10–59 t), enabling fast attachment changes without leaving the cab. It is designed for operations requiring frequent changes between buckets and other compatible attachments, including earthworks, trenching, road construction and site preparation.
The hydraulic coupling mechanism supports efficient attachment handling, while the S-Standard interface provides compatibility with attachments using the matching connection size. This makes the coupler a practical choice for contractors using one excavator for multiple tasks throughout the working day.
